Converter valve monitoring method, device and equipment

The invention discloses a converter valve monitoring method, device and equipment, and the method comprises the steps: carrying out the mathematical modeling of the characteristic parameters of a converter valve after the characteristic parameters of the converter valve during the normal operation are obtained, and obtaining a converter valve mathematical model, and obtaining a characteristic parameter range according to the converter valve mathematical model. And establishing a converter valve simulation model through the characteristic parameter range, thereby performing simulation analysis to obtain converter valve fault information. And constructing a converter valve knowledge base according to the fault information. Characteristic values of the real-time characteristic parameters are obtained to serve as characteristic parameter values, and the characteristic parameter values comprise the extreme values of wave recording, voltage, temperature and frequency; when the characteristic parameter value is with
